Destructive testing

They are carried out at the failure of the sample in order to understand the performance of the material's behavior under different forces.

Do you need to certify or measure any mechanical property of your plastic material?

Weld properties are often the most important because virtually all service conditions involve some pressure or mechanical load.

Determining the mechanical properties of materials is fundamental in many cases for the choice of one material or another based on its behavior. These properties are related to forces outside the material that are exerted on it and respond in one way or another depending on the type of polymer and the transformation process they have undergone.
At CESLA we offer you different solutions to determine the mechanical properties of welding or plastic material. Depending on the need and the field of application of each product, whether for construction, coating, or automotive, for example, mechanical properties will be determined.



Destructive tests



It consists of applying stress in the same direction as the longitudinal axis of the specimens.
The default standard for plastic materials that CESLA uses is DVS 2203-2 (Testing of welded joints between panels and pipes made of thermoplastics).
From all the tensile tests carried out on the universal testing machine, it is possible to extract a graph with the recorded stress-strain data, from which the elastic and plastic behavior of a material can be determined, as well as its resistance to be quantified, for example. maximum or break.

Bending test

The bending test is carried out on the universal testing machine, also used in other tests such as traction, compression, and bending.

In this case, it is necessary to change the supports and the loading tool. The test consists of subjecting a specimen, supported at the ends, to a force on its perpendicular axis.


Tear test

It is used to determine the force necessary to propagate the tear of a defined cut, from a cut made in a specimen or a specimen with a defined indentation.

The general standards that are usually used are DVS 2207-5. There are other standards that speak of tear tests that apply more to plastic films specifically and that follow standards related to those just mentioned, for example, UNE-EN ISO 6383-2 or UNE-EN 6383-1 and UNE-ISO 34-1 according to the tensile test according to DIN EN ISO 527.


Stripping separation

It is a test method based on the DVS 2203-1 standard used to determine the bond strength of plastic materials in the form of sheets, sheets or plates.

It is applicable to the study of any type of joint, regardless of the method used to join the materials (heat-sealing, gluing, sewing, multilayer joining, etc.).
